What is the largest size file I can create in CS5? I am a textile designer and need to be able to create a file that is 1 yrd x 3.5 yards. The resolution needs to be 300 DPI.

300,000 pixels in either dimension. But you'll need to switch to the PSB (Large Document) file format to work with files that large.

That small a file shouldn't be a problem at all.
But do you really need 300 dpi for something that large (probably a poster or banner)? Think about how far away people will be from it when viewing it.
